UNIT POWER PLANT FOR MO'OR-'UEI-ILS.

Patented Dec. 26,

-Application filed Augustl, 1915. Serial No. 45,589. `To all fwltpmz't may concer-a Be it known that l, 'ARTHUR C. MASON, a citizenV of the United States, and a resident of the city-of Flint, county otvGenesee, and

State of lt/lichig'an, have invented certain new and useful Iimurovements in Unit Power Plants for Motor-Vehicles, of which the fol lowing is atull, clear, and exact description.

One of the objects of my invention is to provide a structure by means of which the several elements which go to make up an automobile power plant, can be readily assembled and, disassembled.

Anotherobject is to form a composite supporting frame, so that the central the frame willv serve as a supporting means for the other'portions.

Other objects will appear from the following' description and claims.

The invention consists various elements of a motor vehicle power .plant in such relation to each. other that they muy be easily assembled andr disassembled and in such manner that the ments may be removed without materially disturbing the other elements thereof. Briefiy this power plant comprises an engine)l transn1ission,fy wheels and universal joints, the .transmission removable brakes which are secured to the engine'proper. The parts supporting the transmission also brake operating mechanism, all of which will be clearly understood from the following description taken in connection with the 'accompanying drawings in which similar reference characters refer to similar parts in the several views.

liigure 1 is a side elevation of my improved unit powerl plant. Fig. 2 is a plan View` thereof. Fig. 3 is an inverted plan View of one of the side and central supporting parts. Fig. 4 is an end elevation of the truss frame. i

Referring to Figs. 1 and 2, E represents the engine, C the clutch mechanism 'and the transmission. The supporting frame comprises two parts 10 and 11 arranged on either side of the engine shaft A. These vparts are secured respectively by'any suitable means to the sides K and L of the chassis. `Brackets 12 and 13, preferably integral with the crank case B et tl 1e engine entend at right angles to the vertical sides of the enportion of in combining theV separate elebeing supported by support the clutch und` gine and these brackets are secured by boite 15 and 16 to the inner armsA of the supporting-bracketsl() and 11. Similarly Von l opposite y disposed arms 17 and 1"' is journaled in brackets 30l and 31 which secured to the supporting members 10 and.

11. 0n one .side of the central supporting frame is provided means for removabiy se curing the soif-starter S.

From the above. description, it will ne seen that my invention comprises a'poiver plant of.vr novel design and arrangement and the parts are so arranged that the various sie ments maybe easily removed for repa adjustnumt without materiali.Y disturb the general arrangement of the other pari, while at the sa ie time When compieieiy ssembled, the supporting brackets and truss frame form a rigid and eiiicient support 1 the transmission and clutch operating a'nism.

Having now described my invention, what lf claim as new and desire to secure by Llei;u ters Patent,is:- v

1. In an automobile, a supporting tramo consistilrg ota pluraiityof parte, a center trame consisting of tivo parts one upon each side of the engine each of which. is renier-- ably supported upon the chassis. i

'2. ln' on automobile, a supporting consisting of a plurality of parts, a ce ter frame eensietiugof two separate parte one upon each side of the engine, ach of which is removably supported upm: a V-shaped strut removaiiiy 5 apex to (he upper part of the and removably secured the extremities its simportingiarms respectively to the parte forming; the center frame. 3. Inr an automobile, .consisting of a plurality oparts, a center rame consisting of two separate parts, one upon each side of the engine, each of wb.M is movably supported upon the chassis and a strut removably secured to the engine and' to the center frame.

4c. In, an automobile,

a supporting a supporting frame consisting of a plurality of parte, a center frame consisting of two separate side parts @zich of which. is removably supported upon the chassis, and a self starter removably se- Y cured to one of the side central frames.

In Witness whereof have hereunto set my hand at the borough of Manhattan, clty,

ARTHUR C. MASON.

In presence of ETHEL D. BARON, JOHN 4J. RANAGAN.
